Tire tread



FIG. 1 is a perspective view of a tire, showing my new design, it being understood that the pattern shown repeats uniformly throughout the circumference of the tread;

FIG. 2 is a front elevational view thereof;

FIG. 3 is a right side elevational view thereof, the opposing side being a mirror image thereof; and,

FIG. 4 is a fragmentary frontal view thereof showing the tread pattern in greater detail.

The broken line showing of environment is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a “tire tread,” as shown and described.
